' SLEEPING-BAG.

To all whom it may concern:

Be it known that I, LOUIS JACOBS, a citizen of thellnited States, residing at Chicago in the county of Cook and State of Illinois, have invented certain vnew and useful Improvements in Sleeping-Bags, of which the following is a specification.

This invention relates to improvements in sleeping bags and more particularly to a bag intended for outdoor use and arranged to provide ample protection to the user from the elements. a

One of the objects of my invention is to provide a sleeping bag in which the head portion is held in erected position by a collapsible frame forming a sort of tent structure for the protection of the users hcad.

Another object of the invention is to provide such a device in which the head structure is provided with a canopy held in position by a collapsible frame permitting, when so desired, the completevinclosure of the head structure as a protection from stornn Still another object of the invention is to provide such a sleeping bag which may be readily used either as a stretcher or as a hammock.

A still further object is to provide such a sleeping bag of sturdy, rugged construction providing complete protection to user and at the same time of such a character to permit its being readily folded into small space for transportation.

Still other andfurther objects will become readily apparent to those skilled in the art from a consideration of the following description and drawings wherein:

Figure 1 is a perspective view of my improved sleeping-bag with the cover thrown back and the canopy erected.

Fig. 2 is a perspective view of the head portion of the bag with the canopy thrown back.

Fig. 3 is a perspective view of the head portion of the bag with the canopy erected and connected to the cover for complete protection against storm;

Fig. 4 is a perspective view of the head structure supporting frame.

Referring now to the drawings where I have illustrated the preferred embodiment of the invention, the numeral 10 indicates the bottom of a sleeping bag of generally rectangular outline and of dimensions such Specification of Letters Patent.

the envelop from the bottom portion proriding a reinforcement as well as material in which to insert gromets 17 by means of which the bag may be staked out on the ground or suspended on poles to form a stretcher. The gromets in'the end of the marginalstrip 16 may be utilized for connectionwith a spreader should the user dcsire to suspend the bag in the manner of a hammock.

The cover 15 is seamed to the side-walls and bottom end wall for a short distance from the foot to form a permanent inclosure for the lower end of the envelop and its remaining portion is detachably secured to outer, upper edge portions of the sidewalls 11 and 12 by means of the glovefasteners 19-19. The connections between the sides and bottom'arc suitably seamed and to further strengthen the structure, I

have extended reinforcing strips 20 across the bottom of the bag between opposite pairs of grometsll'.

At the head portion of the bag I have increased the height of the side walls 11 and 12 as at 21 and 22 and similarly in creased the height of the end wall 13 so as to provide a deeper envelop at this portion than throughout the body portion of the bag. erected position by means of a collapsible wire frame illustrated in Fig. fl: comprising a rectangular end section 23 corresponding in width and height to the end member 13 of the bag and side-members 24 and 25 pivoted at 26 upon the vertical bars of the end frame This frame is indicated in Fig. 2 and-the upper edges of the sides 21 and 22 are folded over as at 28 to engage bars of the side frames 24 and 25 being secured in this position by means of the glove-fasteners 29.

A canopy or head cover 30 extends from the upper edge of the head end 18 to form a roof or shelter for the head portion of the bag, it being seamed to the upper edges of the sides for a short distance to a point indicated at 31 and from there on is separable from the side walls so that itmay be thrown The head structure is held in the canopy on the line indicated at 33 and at its ends is provided with loops 3i into each of which is linked the looped ends of a pair ofrods 35which' may be stuck into the ground as indicated in Figs. land 3 to support the canopy in erected position. The forwardly extendingrods 35 engage loops fcrmed bybending inwardly the ends ofthe side-frames 2i and 25 of the frame inIspaced-apart or opened out position. A pair of rings '37 are secured to the outer-end portion of the canopy forcooperation with snap-fasteners 38 secured to the end portion of the cover 15 so that they may be fastened together as indicated in Fig. 3 to completely inclose the head structure and protect the user from the elements. Ventilators 39 are inserted in'the side-wallsof the head structure to provide a supply of fresh air when the hood closed.

In use the bag may be placed uponlthe ground with the cover thrown back as indicated in Fig. 1. The user may then erect the head canopy in which ever position he may desire depending upon the weather and can then place his-blankets within the envelop and after lying down, draw up the cover and snap it in position in engagement with the side walls. The head canopy may then be altered tosuit his convenience, being either-thrown back as indicated in Fig. 2 affording no protection, elevated to the position shown in F'g. 1. or drawn into the position shown in Fig. 3 completely protecting him from storm. I

To collapse the structure-the snapfasteners 29 are disengaged freeing the sides of the head frame and permittingtheir being folded inwardly against the back-frame 23. The entire bag can then be rolled up about this frame forming a rectangular pack easily carried and occupying but little space. V

lVhereas I have illustrated and described but a single embodiment of my invention, it will be evident to those skilled'in the art that many modifications or changes may be made therein, without departingifrom the spirit of the invention or the scope of the appended claims.

Having described my invention, what- I claim is: l
